Definitions

  • the invention relates to a filter cleaning with a flap element according to the preamble of claim 1.
  • the basic principle of filter cleaning is that the respective filter chamber with the filter half to be cleaned is first separated from the suction air flow of the suction turbine and then subsequently a false air flow, which is obtained from the blow-off of the suction turbine, is pulsed into the filter chamber to the outside with protective parts to clean the loaded area from inside to outside.
  • Such a filter cleaning is known with the older patent DE 199 49 095 C2 of the applicant.
  • the control of the false air flow is such that by exploiting pressure differences between the suction air flow and the atmospheric pressure arranged in a housing, designed approximately X-shaped flap element abruptly changes its position and one or more openings in the housing opens and / or closes, so that the secondary air flow impulsively arrives at the one filter half to be cleaned, while the other half of the filter remains in the suction air flow.
  • the EP 1 118 303 A2 shows a similar, pressure-controlled switching of the flap element, which is associated with the same disadvantages.
  • an approximately Y-shaped flap element consisting of two flap parts arranged at an angle to one another, is then controlled by a cost-effective servomotor drive.
  • servomotors are widely used in model making, they can be used inexpensively for the purposes of the invention
  • the servo motor has a drive arm which engages an associated U-shaped receptacle on a lug of the flap element and brings it into one or the other pivotal position.
  • a central position of the flap element namely a central position of the flap element, a left and a right.
  • both filter halves are flowed through by the contaminated stream and are therefore both in function, while in the right pivot position ( Figure 2) only the right half of the filter remains in function and cleans the contaminant flow, while the left filter half of the pulse-generated reverse flow in the opposite direction is cleaned to the dirt cleaning direction.
  • the exhaust air cleaning flow is induced by the sudden opening of a control flap or a control port, wherein an electromagnetically actuated solenoid is used to control this control valve.
  • the invention is characterized in that an electromotive, electromagnetic or otherwise arbitrarily controllable
  • Flap element can be brought into three different pivot positions and this is given a neutral position, in which both filter halves are in operation. Furthermore, the invention is characterized by the fact that either one or the other filter half can be cleaned by switching by means of the electric motor drive.
  • Another advantage of the invention is that for the flap control of Abcuris Kunststoff a single solenoid is present, which operates this single flap, while in the prior art, two different electromagnets with two different flaps were present.

  • the filter halves 1, 2 are sealed from each other and are either operated in parallel, or it can be cleaned one half and the other half of the filter can be used.
  • the container 6 is the drawing simplification because of very short and with low volume drawn. It can also be designed as a bag or as a very large container, wherein it is important that the entire ring filter is taken in the region of a bottom-side seal 7, to provide an inner filter space.
  • the switching element according to the invention consists of a Y-flap 9, which consists of two mutually angularly arranged partial flaps 10, 11, which are rigidly interconnected and are pivotally mounted in the region of a pivot bearing 12. At the pivot bearing 12 is rotatably connected to a lever 13, which opens into an upper fork 14 open at the top.
  • the lever 13 with the fork 14 engages sealed in a chamber housing 42, through which flows the impulsively generated Abcuris Kunststoff through.
  • the drive axis of the servo motor 36 (see Figure 4) is rotatably connected to an actuating pin 15 which is disposed on a pivot member which is pivotally mounted in a pivot point 16 on the housing of the vacuum cleaner.
  • the actuating pin 15 engages the fork 14 and is by pivoting operation of the lever 13 in a position to pivot the Y-flap from a neutral position to one side or the other.

  • the outflow openings 31, 32 are air-conveying part of a collecting channel 37, so that the air flowing in through the two openings 31, 32 air is sucked in the direction of arrow 22 from the suction port 20 of the suction turbine 19, is compressed there and leaves the exhaust port 21 in the indicated direction of arrow 35 , Thus, the air flowing into the filter chamber 38, 39 is sucked in the direction of arrow 22 by the suction turbine 19 via its intake opening 20.

  • the partial flap 11 closes the outflow opening 32 and only after complete closure of the outflow opening 32 the lifting magnet 18 is actuated, so that the impulse flap 17 abruptly from the opening 29 is released and in the Overpressure 24 collected over-pressure air now abruptly flows through the opening 29 in the direction of arrow 30 down into the chamber 42 and this enters the channel 26, which can flow the pulse air in the direction of arrow 34 in the left Schmutzsaugerraum and directed in the direction of arrow 34 from the inside to the outside flows through the left filter half 1 and this cleans it.

Abstract

L'invention concerne un nettoyage de filtre dans un aspirateur de saletés avec un élément à clapet commutable, le nettoyage du filtre ou de parties du filtre ayant lieu par amenée d'un flux d'air parasite sur le côté intérieur du filtre à nettoyer. Les filtres étanchés les uns par rapport aux autres sont parcourus séparément dans le contenant d'aspirateur de saletés de l'extérieur vers l'intérieur et un élément à volet disposé dans un logement de chambre peut être basculé, son basculement fermant et libérant des ouvertures. Le flux d'air parasite parvient à la manière d'impulsions sur la surface à nettoyer du filtre de l'intérieur vers l'extérieur. L'invention est caractérisée en ce que l'élément à clapet est constitué d'au moins deux clapets partiels dont le basculement est provoqué par un entraînement de basculement, en ce que le clapet concerné ferme sélectivement l'ouverture d'écoulement de la chambre de filtre concernée en direction de l'ouverture d'aspiration de la turbine d'aspiration, en ce que le côté échappement de la turbine d'aspiration transporte l'air surpressurisé produit dans une chambre de surpression dans laquelle est disposé un logement de chambre qui présente au moins une ouverture que doit ouvrir et fermer un élément d'entraînement actionnable brusquement et par laquelle, lorsqu'elle est ouverte, l'air surpressurisé pénètre sélectivement en traversant le logement de chambre dans un canal d'impulsion de dérivation qui introduit celui-ci pour le nettoyage dans l'une ou l'autre chambre de filtre.
